Null Pointer when adding child to OMElement

2007-10-10 Thread Chris Bowman 

Hi,
I am trying to add a simple child element to an OMElement I have 
created, but I am getting a null pointer. I am using the same syntax I 
have seen in the Axiom OM Tutorial 
(http://ws.apache.org/axis2/1_0/OMTutorial.html), and am using Axis 2 1.3.


The code I try is:

public static OMElement createQuery(){
  OMNamespace aon = new 
OMNamespaceImpl(http://www.aoi.com/WSDA/0.1;, ao);

  OMElement wsdaQueryNode = new OMElementImpl(wsdaQuery, aon, null);
  wsdaQueryNode.addAttribute(name, campaign.getProductSkuId, aon);
  OMElement param = new OMElementImpl(param, aon, null);
  param.addAttribute(skuId, 6949, aon);
  param.addChild(param);
  return wsdaQueryNode;
}

The error I get is:

java.lang.NullPointerException
Error: java.lang.NullPointerException

org.apache.axiom.om.impl.builder.StAXOMBuilder.init(StAXOMBuilder.java:64) 

  at

  at 
org.apache.axiom.om.impl.llom.OMElementImpl.addChild(OMElementImpl.java:197)

com.aoi.ws.clients.test.WSDATestClient.createQuery(WSDATestClient.java:55)

  at com.aoi.ws.clients.test.WSDATestClient.main(WSDATestClient.java:27)

Any ideas would be much appreciated.

Regards,

Chris

Hi,

This will work.

public static OMElement createQuery(){
OMFactory factory = OMAbstractFactory.getOMFactory();
OMNamespace aon = factory.createOMNamespace(
http://www.aoi.com/WSDA/0.1,ao;);
OMElement wsdaQueryNode = factory.createOMElement(wsdaQuery, aon,
null);
wsdaQueryNode.addAttribute(name, campaign.getProductSkuId, aon);
OMElement param = factory.createOMElement(param, aon, null);
param.addAttribute(skuId, 6949, aon);
wsdaQueryNode.addChild(param);
  return wsdaQueryNode;
}
